To make or break "THE IMAGE" at international level you need the decades of hard diplomatic work !!!! It can't be done in fortnight !!!!!
Like it or not world doesn't run on morals. It run on invested interests. Yes "invested". What you can offer decide your value. Economically & politically. For both India is way head now. It's hard to catch up.
And thanks to the "NON STATE" actors
Evenif nobody is going to award you " State sponsoring terrorism" as of now but your image and the current condition in your country make it hard to belive you are the "good guys"
All those who thought that the "congressional committee" on "Pakistan: foe or ally" was nothing but bunch of people babbling !!!!! They documentedly distort your image !!!!
Geographical advantage of Pak is fast becoming irrelevant ( to USA ) as They now see China as threat no 1 than Russia in past. I would bet that in next 5 years USA will be hostile to Pak.
China is Pak's friend but most of time their friendship comes in only when India is involved. And they themselves are facing Image crisis. Genuine or crafted is another subject to discuss
If I can suggest , I will say Pak should forget about Kashmir for few years. Clear your country from State non state actors, establish rule of law. Develope your economy, reach out the world for development and in dacade or so you will be in place where everybody will hear you seriously. Then try help people of Kashmir. FIRST HELP YOURSLEF. Good luck
